Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 4.813819361458333 > 4.730942900390626.
IsChangePoint: Marked as a change because one of 4/12/2022 3:59:36 PM, 4/19/2022 4:53:57 AM falls between 4/10/2022 3:30:35 PM and 4/19/2022 4:53:57 AM.
IsRegressionStdDev: Marked as regression because -1530.5236883896464 (T) = (0 -4814200.206092978) / Math.Sqrt((67493.55880416646 / (18)) + (848357.9621780615 / (23))) is less than -2.0226909200346674 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (18) + (23) - 2, .025) and -0.06847451830996708 = (4505676.198724626 - 4814200.206092978) / 4505676.198724626 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
